Eagles cornerback Nnamdi Asomugha was carted off the practice field after he suffered a left knee injury on Thursday.

The team said Asomugha would undergo further evaluation before it made a final diagnosis. He was listed as a partial participant in practice. His status for Sunday's game against the Patriots was unclear, though, after he crumbled to the turf during a non-contact play.

Cornerback Joselio Hanson said that he was told the injury wasn't serious.

How confident would you be in the Eagles pass defense against the Patriots if Nnamdi Asomugha is unable to play?

Not confident at all. Tom Brady will carve them up like a Thanksgiving turkey.598 (68.5%)

A little confident. Joselio Hanson looked good last week and Brandon Hughes can do a decent job.192 (22.0%)

Very confident. The defense is on a roll and shut down the Giants’ better-than-average passing game.83 (9.5%)

"It looked bad, but they said he was going to be alright, expecting to come back tomorrow and practice," Hanson said.

The Eagles are already down a cornerback with Dominique Rodgers-Cromartie out with a high ankle sprain. Hanson has filled in for Rodgers-Cromartie as the nickel corner, but said if Asomugha couldn't go Sunday he would move outside in the base defense and play in the slot on nickel downs. Brandon Hughes would then take Hanson's spot on the outside.

Rookie Curtis Marsh is another option.

“Brandon – he’s really good and he’s coming into his own with more game experience,” Coleman said. “With Curtis, he’s athletic. He loves to be able to get up there and bump and run and he has the speed to run with any wide receiver.”

The Eagles' secondary already had a number of difficult matchups with quarterback Tom Brady and his bevy of receivers coming to town. Asomugha's injury only further complicates defensive coordinator Juan Castillo's game planning.

Castillo has used Asomugha is many different ways this season. He was expected to help out with covering the Patriots' lethal two-headed tight end duo of Rob Gronkowski and Aaron Hernandez.

“There are different packages that we have," Castillo said before Asomugha's injury. "And I think that they know, sometimes Nnamdi will be there, sometimes he won’t be there. It could be two guys or one guy or maybe a safety. The thing is they’ve seen all those things so you’re not going to trick anybody.”
